Post DIY service and repair guide for; Kestrel/Deltalyo DAS6.

This guide covers:
  1. How to inspect and replace the main bearing.
  2. How to inspect and replace the carbon brushes.
  3. How to fix a split flex leads.

I ordered these from clean your car: http://www.cleanyourcar.co.uk/polish.../prod_722.html



Cost
DAS-6 Bearing - £5.95
DAS-6 Brushes - £5.95
Total Tax: £3.88
Shipping: £12.95
Total £28.73 - €38.83

#1 - How to inspect and replace the main bearing.

With the backing plate off unscrew the counter weight screws



Remove the counter weight



Don't loose the highlighted washers.



Place all parts into the baggie supplied with the brushes.



With some force pull the bearing up and out of it's housing.



Old VS New



Below is a video on how to check the operation of the bearing.
Excess play and noise is sign of a bearing in need of a replacement.
left is the old worn bearing / right is the new unused bearing.



To refit or replace the bearing follow the above guide in reverse.

#2 - How to inspect and replace the carbon brushes.

First remove this screw from the back of the machine.



Now pull back the black section form the front red section, splitting the two housings.




Run the black housing down the lead and out of the way.



On the left and right sides of the machine you will see the brush mechanisms. Here the brushes are pushed onto the armature from the downward pressure of springs arm, they are connected to the electrical circuit with a female spade connector.
I will cover one side as the process is the same for both.

Unscrew the retaining screw.





And pull up the mechanism and it's spacer.



Bag all the removed parts. ****



This is the mechinisum removed to the side of the machine.



With force pull the spade connector away from the pin.
I had to use a screw driver to brake it free.



Now pull up the brush by its wire out if it's housing.



Good brushes should be flat and smooth, brushes that have corners chipped off are bad.

Left is the old brush right is the new brush





to refit or replace the brushes first the arm of the spring needs to moved out of the housing. Here i used a skewer, i cut the tip off so the top was flat, a butter knife is another idea.



With the arm up now push it off to this side.



Now place the carbon brush into the housing.



reattach the spade connector and screw down the retaining screw.

To refit or mechanism follow the above guide in reverse. ****

#3 - How to fix a split flex leads.

One common problem with machine polishers is that the leads brake inside the flex, this happens mostly right it the back of the machine and this is due to the constant movement at that point, think of bending a piece of wire between you hands it will snap if you keep bending it in the same place.

This is the symptom of a brake in the leads of the flex.

I have taken the back of and checked the connection of the wires going in. Nothing loose in there.

Any other ideas anyone?



With the black housing separated from the rest of the machine you can see the wire of the flex.



remove the screws from the clamp



follow the blue and brown wires into the machine.



Loosen the screw enough so you can remove the Banana Spade connector


http://mxvaleting.ie/diy-service-and-repair-guide-for-kestreldeltalyo-das6/
Don't remove the screw as it will be difficult to refit



From here cut the flex below the high lighted area about a hands width to be safe.



From here on you will have to let your electrical know how lead you on as i did not have the tools on hand to show the rest

I've learned alot from different forums and from here also, this is my way of paying it forward.

Thanks for looking.

Nice write up.
An alternative to replacing the bearing/hub assembly is to purchase some 6001rs or 6001z bearings. You can pick them up for as little as 10 for £5.
Remove bearing assembly as per instructions. Press out the hub from the old bearings and press on two new ones. Refit bearing.
Job done.

I though of that also but it's more effort but you do get more bang for buck I guess buying seprate.

I'm glad you like the write up.

It only takes a minute to remove and replace the hub so the time should not be an issue.
It also gives the option, If required, of using really good quality bearings SKF and the like, for no more than the cost of a new bearing assembly.

As they say a picture paints a thousand words. I'm not sure how often people appreciated how much effort goes in to something like this. It must have taken some considerable time to have put it all together, great photos and text, an excellent job.

For me I'd have had to go to my mechanic and it was easier to just buy and fit the lot.

About four + hours went into making this but from what I've gained from this site it's a small repayment.
